Red Sox outfielder Ryan Kalish’s long battle with injuries continues.
Kalish, 24, is set to again undergo surgery on his right, nonthrowing shoulder, with Dr. Lewis Yocum performing the operation.
Kalish had shoulder surgery last offseason after suffering a torn labrum, and that was after surgery to repair a bulging disk in his neck.
It was thought that resting this offseason would alleviate the pain Kalish was experiencing, but when he started to swing a bat earlier this month, the discomfort returned.
Kalish was expected to be Boston’s fourth outfielder to start the season, but with him out for the foreseeable future, Daniel Nava’s chances of filling that role are enhanced.
According to WEEI.com, the Red Sox signed outfielder Ryan Sweeney to a minor league contract Friday, with an invitation to spring training. Sweeney, 27, was nontendered by the Sox after hitting .260 in 63 games in 2012, his season ending when he broke his hand punching a door in the clubhouse July 30.
Kalish hit just .229 with three doubles and three steals in 36 games last season, but the injury limited him to 13 plate appearances in September.
